Almost a century after the Halifax Explosion, people are still sharing stories about one of the worst disasters in Canadian history. But now those stories come equipped with a hashtag.

To commemorate the 95th anniversary of what was, at the time, the worst human-made disaster in the world, the Nova Scotia Archives is collecting people's family history of the event, 140 characters at a time.

For the past few years, Nova Scotians have been tweeting stories about the Halifax Explosion to the archives. Amazed at some of the personal history they were uncovering and recording, the archivists decided to make it official.
